Humminbird Transom Transducer for HELIX with MEGA Down Imaging+ and Dual Spectrum CHIRP – XM 9 HW MDI T

Upgrade your HELIX sonar with the Humminbird XM 9 HW MDI T transom transducer, an all in one solution that combines MEGA Down Imaging+ and Dual Spectrum CHIRP 2D sonar. Designed for HELIX models, this transom mount brings together depth, clarity, and temperature sensing in a single package that can adapt to a range of boat setups.

MEGA Down Imaging+ delivers remarkably clear imagery across the water column. In its high resolution modes, you can explore from the surface down to about 200 feet with enhanced detail that helps you spot structure, cover, and fish-holding areas. The Dual Spectrum CHIRP 2D sonar adds clean returns and strong target separation, offering reliable readings at longer ranges up to 1200 feet. This combination gives you two complementary views to interpret underwater features more quickly and confidently.

Compatibility is at the core of this package. It is engineered for HELIX G3N and G4N models that feature MEGA Down Imaging+. The built in temperature sensor adds environmental context to your sonar data, helping you time approaches and interpret displays with a fuller picture of the surroundings. The transducer ships with a 20 foot cable, keeping your mounting options flexible whether you are at the bow, stern, or midship rigging your HELIX system for optimal viewing angles.
